I'm not sure what aluminum tape you have looked at/used, but the heavy HVAC stuff works pretty good at sticking as long as you get the surfaces CLEAN. Maybe a wipe down with naptha or even acetone to get the surface oils off. The problem I could see is it not holding the weight. Since it was not designed to hold much weight you might need to run some vertical sheet metal strips to hold the weight.
Thanks, Kenny.
I got some thin stuff by mistake after I ran out of the first roll of heavier stuff. It didn't seem to be as tacky and it tore easily or, at least in my mind, that's how it seemed. In fact, I just sprayed the panels and wiped them down and put some of the thing stuff back up. It stuck but it didn't feel as substantial. We'll see how it holds.
